`matherr' never causes the program to abort; if you want to abort the 
program, you need to do it yourself in the version of `matherr' you 
supply.

In general, `matherr' is not supposed to abort the program, just to cope 
with numerical errors so that the program does NOT abort in the first 
place.

Did you read the docs of `matherr'?  If not, I suggest to do it, 'cause I 
think it will answer many of your questions.  From the DOS prompt, type 
"info libc matherr" and read there.  Additional info is available by 
typing "info libc libm".
